Field monitoring of hydraulic fractures is currently expensive, and the recorded data is often
limited to reflect fracture networks, implying the necessity of utilizing additional evidence to …

This paper extends the discontinuous deformation analysis (DDA) by using an additional
evaluation of edge-to-edge contact, with the aim that it can be used to accurately model the …

Dynamic friction degradation of the sliding surface in large earthquake-triggered landslides
is widely assumed, especially for high-speed and long run-out landslides. But there are few …

We use the numerical, discrete element, Discontinuous Deformation Analysis (DDA) method
to study velocity-distance evolution of the catastrophic Vajont landslide using a newly …

The present study develops the numerical manifold method as a tool to investigate the
progressive failure in rock slopes. The entire processes of the progressive slide surface …

Discontinuous deformation analysis (DDA) method is a discrete element method, presenting
a great advantage in modelling deformation and rigid body movements, and it is also an …

Fracture and fragmentation of rock under various loadings or in multi-field conditions are
important topics in many rock engineering scenarios. Numerical tools are commonly applied …

This study introduces the vector sum method into discontinuum-based methods by
considering the sliding vector and the stress state of the discrete block system. The sliding …

In this paper, a discontinuous numerical model, namely SDDARF 3D (three-dimensional
spherical discontinuous deformation analysis for rock failure), is proposed for simulating the …

The right bank slope of the Dagangshan hydropower station has undergone large
deformation during excavation, which may continue to increase and cause slope instability …
